Haynes says the best part is that the video shows Elsa's "unmitigated commitment to helping get the truck unstuck."

Diners at the restaurant watching the mired police wagon could be heard laughing in the video as Triplett tried to push the vehicle out of the snow and gestured to the driver to turn the vehicle's wheels.

A Boston police spokesman says the officers in the stuck vehicle "would like to thank the Elsa-impersonator for the assist."
